A computer-implemented broker entity (7) for conveying state information from a technical system (1) as a producer to a requesting device (2) as a consumer, wherein the state information comprises a plurality of values that have been measured and/or generated by components of the technical system, each value is associated with a given semantic meaning, and the broker entity is configured to: • receive, from the requesting device (2), a request (3) for one or more target values (6) of state information that have sought target semantic meanings (6a); • obtain, from the technical system (1), one or more source values (4) of state information that are associated with given source semantic meanings (4a); • obtain, at least in part from a transformation library (5), one or more transformations (5a-5c), wherein each transformation (5a-5c) maps one or more first values that are associated with first semantic meanings to one or more second values that are associated with second semantic meanings; • apply the one or more transformations (5a-5c), or a new transformation (5*) obtained based on the one or more transformations (5a-5c), to the source values (4) of state information, thereby obtaining the one or more target values (6) of state information; and • transmit the one or more target values (6) to the requesting device (2).
